S1·E150 Chand Par Hatya Part 1

A mission to the moon is undertaken by three astronauts. They eventually prepare to launch to the moon. Nevertheless, we learn that there is a disagreement between them and that there is something going on between them. Later, when someone shuts off the oxygen pipe, one of the astronauts, Kumaresh, dies. Was he killed by Adish? Or was it another person?
